China Universal External and Internal M1432 Cylindrical Grinding Machine for Sale
Description
FEATURES of our Universal Cylindrical Grinding Machine:
When conical grinding, the table can be swivelled to either side and exactly positioned by using the scale
Oil film between bearing and spindle keeps vibrations at a minimum level, hence achieving outstanding results and top accuracy
Precisely balanced spindle head and solid grinding head guarantee extraordinary results at any type of operation
Strong reinforcements and solidly designed panels of the machine base makes it resistant to temperature fluctuations and deformations
Spindle is mounted from both sides and features adjustable sliding bearings consisting of three segments
Hydrodynamic bearing of spindle, therefore no contact between spindle and bearing
Longitudinal table feed can be set to automatic mode – hydraulically driven or manual mode – by handwheel
Stepless feed adjustments with the option of a programmable hold time at the end of each table movement
Hydraulic or manual repositioning of grinding spindle stock
Guideways in x- and y-axis are precisely constructed and hand-polished
Longitudinal table guide and cross guide of grinding headstock each feature a V-guide and flat guide
